Specificati'ori of Letters Patent.

Application filed March 24, 1906. Serial No. 307,785.

To all whom it may concern:

Be it known that I, Mon'roN Havens, Jr.', of Albany, in the county ofAlbany and State of New York, have invented a certain new and usefulBranch Box, of which the following is a specification.

My invention has for its object the productionof a branch box forelectric wires, which is particularly simple and economical inconstruction, and highly eflicient and durable in use; and to this endit consists in the novel ctnnbinat-ions and means hereinafter set forthand claimed.

In describing this invention, reference is had tothe accompanyingdrawing in which like characters designate corresponding parts in allthe views.

Figure 1 is an elevation of a preferable construction of my branch box,a conduit and a pair of wires being shown inoperative relation thereto.Fig. 2 is a plan of the body of the branch box. Figs. 3 and 4 aresectional views taken, respectively, on

lines AA and B-B, Fig. 1. Fig. 5 is a.

sectional iew taken on line C-C, Fig. 2. Fig. 6 is an inverted plan ofthe closure.

' The body 1 of my branch box is preferably hollowand elongated, and isformed of metal and provided with an opening 2 in one side thereof, andwith an inlet passage 3 communicating with the interior of the body.Opposing lengthwise portions of the inner face of the body are'providedwith diagonally arranged lugs 4 formed with threaded sockets 5 extendingthrough the outer and inner faces 6, 7 thereof. These faces 6., 7 aredisposed between, and spaced apart from, the planes of the open s1de ofthe body 1 and the wall 8 opposite said open passage 3 is shown asextending laterallyfrom the body 1 it is obvious that the branch box mayhe provided with one or more passages extending either downwardly orIon-- gitudinally. 1

The open side of the body 1 is provided with an elongated closureusually formed of a single piece of insulation, as porcelain, andprovided with one or more perforations 12, for permitting the outlet ofone or more of the wires 10, the illustrated construction of the closurehaving perforations 12 in its ends for the outlet of both wires 10. Said1 closure 11 is also provided with an elongated reduced portion 13inserted into the opening 2, and having its inner face opposed to, andengaged with, the outer faces 6 of the lugs 4. A ledge 14 is provided onthe closure 11 at the base of the reduced portion 13 and is opposed to,and spaced apart from, the edge 15. Any suitable connecting means, asscrews 16, are passed through openings 17 in the closure 11 and into thethreaded sockets 5 of the lugs 4 for detachably securing said closure'tothe body 1.

By constructing the body 1 and the closure 11 as described, liability ofbreakage of the more or less fragile closure is reduced to a minimum,since said closure engages the body only atseparated points and in closeproximity to the securing screws 16, and is formed of full thickness atsaid points of engagement. Moreover, the threaded sockets 5 are readilyand cheaply formed with a minimum liability of injury to the tools usedin the formatioh of said sockets.

What I claim is fl A branch box for wires comprisinga hollow elongatedbody formed with a passage for the inlet of the wires, and with an openPatented Jan. 16, 1912.
